Demonstration of Pressure Wave Observation by Acousto-Optic Sensing Using a Self-Mixing Interferometer
In this paper, we demonstrate that a compact and inexpensive interferometric sensor based on the self-mixing effect in the laser cavity can be used for the characterization of shock waves. The sensor measures the changes in the refractive index induced by the shock wave. It is based on the self-mixi...
